As Kevin says, point the camera at the sun at your own peril! Having said that I've never had a problem with wide angle lens/slow normal lenses (so long as you don't keep it pointing at the sun). Problem comes when there is a bit of aperture, like a telephoto. You can see @alex1320 's reply in https://steemit.com/steemstem/@terrylovejoy/venus-at-inferior-conjunction .
